The multifocal Visual Evoked Potential (mfVEP) is used in clinical diagnosis and basic research. Employing steady-state stimuli rather than the usual m-sequence stimuli may simplify statistical evaluation and reduce examination durations. In one aspect, this study attempted to optimize the ssmfVEP by comparing different pattern densities to check if the response was increased for smaller regions. The ssmfVEPs results showed that the larger regions gave larger responses and spatially sparse stimulation did not improve the response when coupled with continuous stimuli. Additionally, this study...
